With NFL Free Agency kicking off about a month ago, many Teams have looked to plug holes that their team had last season. They will do so even more once the NFL Draft starts on April 26.

Here are the teams that have been most active in adding new players, whether through free agency or trades, so far in the offseason.

Chicago Bears

  • Additions: Tyler Bray - QB, Trey Burton - TE, Chase Daniel - QB, Bennie Fowler - WR, Taylor Gabriel - WR, Aaron Lynch - DE, Cody Parkey - K, Allen Robinson - WR, Earl Watford - G

The Bears have mostly used free agency to upgrade the weapons for second-year quarterback Mitchell Trubisky to throw to.

The two main ones, Robinson and Burton, do come with risks though. Robinson tore his ACL in the very first game last season, and Burton has never been a full-time starter as he was previously behind Zach Ertz in the Eagles’ depth chart.

Cleveland Browns

  • Additions: Darren Fells - TE, E.J. Gaines - CB, Chris Hubbard - OT, Carlos Hyde - RB, Jeff Janis - WR, Jarvis Landry - WR (trade), Terrance Mitchell - CB, Damarious Randall - CB, Chris Smith - DE, Drew Stanton - QB, Donald Stephenson - OT, Tyrod Taylor - QB (trade)

With new general manager John Dorsey in tow, the Browns have made plenty of moves coming off a 0-16 season. They traded for Taylor, who started 43 games under center for the Bills from 2015-17.

They also acquired Landry, a player whose 400 catches with the Dolphins are the most in NFL history by anyone in their first four years. They are expected to take a quarterback with the first overall selection and also own the fourth pick.

Houston Texans

  • Additions: Johnson Bademosi - CB, Sammie Coates - WR, Aaron Colvin - CB, Zach Fulton - G, Seantrel Henderson - OT, Senio Kelemete - G, Josh Keyes - LB, Matt Lengel - TE, Tyrann Mathieu - S, Joe Webb - QB, Brandon Weeden - QB

Texans’ quarterbacks were sacked 54 times in 2017.

It was a priority for Houston to upgrade the offensive line, and they have attempted to do so in signing three new players up front. They jumped at the opportunity to sign Mathieu, one of the game’s best safeties when healthy, after he was cut by the Cardinals.

Los Angeles Rams

  • Additions: Brandin Cooks - WR (trade), Marcus Peters - CB (trade), Sam Shields - CB, Ndamukong Suh - DT, Aqib Talib - CB (trade), Ramik Wilson - LB

While the Rams haven’t exactly been active in signing free agents from other teams (other than signing five-time Pro Bowl defensive tackle Suh after he was cut by the Dolphins), they have been extremely involved in the trade market.

They acquired two cornerbacks in Talib and Peters who have combined to be named to seven Pro Bowls. They dealt for Cooks who has gone over 1,000 yards receiving three straight seasons. They also traded starting edge rusher Robert Quinn to the Dolphins and starting linebacker Robert Ogletree to the Giants.

New York Jets

  • Additions: Teddy Bridgewater - QB, Brandon Copeland - LB, Isaiah Crowell - RB, Neville Hewitt - LB, Charles Johnson - WR, Trumaine Johnson - CB, Spencer Long - C, Kevin Minter - LB, Kevin Pierre-Louis - LB, Terrelle Pryor - WR, Thomas Rawls - RB, Andre Roberts - WR, Cairo Santos - K, Travis Swanson - C, Clive Walford - TE, Avery Williamson - LB

The main acquisition in the Jets’ busy offseason has been Johnson, the former Rams cornerback.

He agreed to a five-year deal worth $72.5 million ($45 million guaranteed). They also made a bold move in trading up for the third pick in a deal with the Colts. They are expected to use it on a quarterback who will battle it out with the newly-acquired Bridgewater and re-signed Josh McCown for starting duties under center.

Oakland Raiders

  • Additions: Armonty Bryant - DE, Tank Carradine - DE, Derek Carrier - TE, Andrew DePaola - LS, Breno Giacomimi - OT, Marcus Gilchrist - S, Senquez Golson - CB, Leon Hall - CB, Dwayne Harris - WR, Josh Johnson - QB, Emmanuel Lamur - LB, Doug Martin - RB, Rashaan Melvin - CB, Jordy Nelson - WR, Keith Smith - FB, Griff Whalen - WR, Tahir Whitehead - LB, Kyle Wilber - LB, Shareece Wright - CB

After a disappointing 6-10 season, the Raiders have signed easily the most free agents from other teams in the offseason.

The biggest name is Nelson, whom they signed after he was cut by the Packers. With Aaron Rodgers out with injury for nine games, he struggled to produce. In his three prior seasons though (missed 2015 due to injury), he caught 280 passes for 4,090 yards and 35 touchdowns.
